Air handling unit cleaning in Berwick, Kent
Air handling unit cleaning in Berwick, surveyed first and signed off with a written report and photos. Call for a fixed quote.
- Plant that needs cleaning after a refit
- Dust built up on fan impellers
- Coils clogged with dust and debris
Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Stick to the filter change plan
- Book the next check in line with the report
- Keep the area around the fresh air intake clear
- Report musty smells from the vents right away
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
AHU cleaning for kitchens and businesses in Berwick
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. If you have coils clogged with dust and debris and fan sections that haven’t been cleaned in years, we can help.
For a building in or near Berwick, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Good records are part of the job. You get a written report with pictures after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Why act early in Berwick
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. If the system at a site near Berwick fails, there may be nowhere nearby to move to.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are unsure, call 0345 646 2711 or email us for straight advice and a fixed quote.

Staff cleaning versus specialist work
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
What we do, step by step
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. The work itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Pictures of the system and its access let us plan the work in Berwick before we set off.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
How to prepare
- Mention any parking or loading restrictions
- Mention any locked doors, roof access or ceiling voids
- Tell us the best time to work, such as after service or at a weekend

Part by part
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.
Fans and fan sections
Dust on a fan impeller adds weight and wear. A clean fan runs more smoothly.
Signs you need AHU cleaning in Berwick
Filters that aren’t changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
These are the problems we see most often:
- Odours coming through the supply air
- Air handling units never cleaned inside
- Drain trays holding standing water
- Debris and leaves in the fresh air intake
For buildings in and around Berwick, TR19® Air cleaning starts with an inspection.
Questions to ask before booking
- Whether the work can be done while the site is closed
- Whether VAT is included
- Exactly which parts of the system are covered
- Whether the price is fixed
Multi-site and managed buildings
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side and send the paperwork to whoever needs it.
Berwick questions
Can a school’s ventilation in Berwick be done out of term time?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 2 schools, colleges and universities with registered kitchens within about a mile and a half of Berwick. Just call 0345 646 2711 or drop us a line with your term dates and we will plan around them.
Can the work in Berwick be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. The work in Berwick can fit around your hours. Your opening times are the first thing we ask for.
Can you look after several sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Each site gets its own report and photos.
Do you clean the ductwork as well?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.
Is there a report after cleaning?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
Is a quote from pictures possible?
Often, yes. With good pictures, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
Which parts of an air handling unit do you clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.
How often should an air handling unit be cleaned?
It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and the report recommends a next date.
